This is dated March 1995 (my birthday in fact; I wasn't actually born in March 1995, I mean that the day is the same). It's a sort of concept slaughter / puzzle level; a cramped lot of stone dungeons wherein you activate trigger lines or shoot walls, and a load of baddies mob you. Starts off fun, but actually gets worse and more irritating as it goes along, until it ends with a literal switch hunt where you have to press 81(!) switches in a featureless grid.
